Formula

For y = a × base^x, compute valueAtX = a × base^x and solve target with solutionX = ln(target ÷ a) ÷ ln(base) when the real-domain conditions hold.

Worked example

Worked example: Inputs: Initial coefficient: 2; Exponential base: 3; x for evaluation: 4; Target y value to solve: 162. Outputs: Function value at entered x: 162; Solution of a × baseˣ = target: 4.
